SetBoundingBox()

void PreProcessor::SetBoundingBox	(	float	upperLeftX,
		float	upperLeftY,
		float	lowerRightX,
		float	lowerRightY
	)

Used to set the bounding box each scene is marked with. Set as float values in range [0-1] indicating fractional coordinates in the image frame.

Parameters

upperLeftX
upperLeftY
lowerRightX
lowerRightY
